#692 closed defect (fixed)

Region Manager broken for blocking when empty

When the region is empty (out of buffers), a task calling get segment should block until memory is available. In the switch to the allocator mutex, the proper protocol for blocking and unblocking a task was not maintained. The attached patch restores that protocol in the appropriate places.
